qhusb_dload brick after bad vold.fstab edit

Sorry if this is the wrong place to post - just wanted to share my unpleasant experience.

I've bricked my phone in a peculiar way - it appears to be a hard brick, non-responsive to any buttons. Plugging in to the computer gets me the dreaded qhusb_dload QPST download mode. Not a good sign.

It wasn't due to faulty ROM flashing, either. I made a bad edit to /system/etc/vold.fstab fiddling with the way the internal and external SD cards get mounted - mmc1 instead of mmc2. After one reboot, I had some sd card corrupted errors. Proceeding to format the card may have been my fatal error. By the second reboot, I was bricked. D'oh. I imagine I had accidentally mounted a partition of the internal emmc that is critical to normal operations, then tried to wipe it.

From what I've read, a USB jig won't do much good, but it's worth a try.

Not sure how the whole exchange process will work in this case. I mean, I can exchange for a different phone, or a new Skyrocket and pay the difference, but I really had my heart set on a cheapo skyrocket. Perhaps if I take this up with Samsung instead?

I didn't expect much in the way of warranties because I purchased this refurbished. With Samsung customer service I didn't have much luck. However, I just got off the phone with AT&T, and they're overnighting me a replacement, which is cool. They have a 30 day policy on any web store items, so I'm covered. Anyways, lesson learned

we need all the help we can get. just a bunch of curious noobs, ya know
the main discovery we did with sensation was to make the emmc visible to any pc it's connected to, then overwriting whatever was messed up (like the hboot) with a stock version of that file.

in theory, you should be able to do this to any phone running on a qualcomm chipset once it's in the qhsusb_dload mode. still lots to test, but anyone is welcome to participate, of course!
